Time interleaving - mattpascoe135/dab GitHub Wiki

#Time interleaving Time interleaving shall be applied to the output of each convolutional encoder for all sub-channels of the Main Service Channel (MSC). It shall not be applied to the FIC.

The output of each individual convolutional encoder is a sequence of convolutional codewords denoted eq. where r is defined as the time index ranging from −∞ to +∞ , whose value taken modulo 5 000 (mod(r, 5 000)) is equal to the logical frame count of the corresponding logical frame. The time index is introduced for the purpose of describing system properties over several logical frames independently of the absolute time. It is notionally related to the logical frame count in such a way that they are aligned at r equals 0.
